AMD Radeon R9 270X Graphics Card Review

At Techgage, we strive to make sure our results are as accurate as possible. Our testing is rigorous and time-consuming, but we feel the effort is worth it. In an attempt to leave no question unanswered, this page contains not only our test-bed specifications, but also a detailed look at how we conduct our testing.

Test Machine

The below table lists our testing machine’s hardware, which remains unchanged throughout all GPU testing, minus the GPU. Each card used for comparison is also listed here, along with the driver version used.

When preparing our test-beds for any type of performance testing, we follow these guidelines:

General Guidelines

• No power-saving options are enabled in the motherboard’s BIOS.
• No virus scanner or firewall is installed.
• The OS is kept clean; no scrap files are left in between runs.
• Machine has proper airflow and the room temperature is 80°F (27°C) or less.

To aid with the goal of keeping accurate and repeatable results, we alter certain services in Windows 7 from starting up at boot. This is due to the fact that these services have the tendency to start up in the background without notice, potentially causing inaccurate test results. For example, disabling “Windows Search” turns off the OS’ indexing which can at times utilize the hard drive and memory more than we’d like.

The services we disable are:

• Windows Defender
• Windows Firewall
• Windows Search
• Windows Update

For further fine-tuning, we also use Windows’ “Classic” desktop theme, which gets rid of the transparency that can sometimes utilize a GPU in the background.

Vendor Favortism

Sometimes, either AMD or NVIDIA will work with a game studio to help their development process along. As history has proven, this often results in a game that is tuned better for one vendor over the other, although sometimes the tides can change over time, resulting in the opposite vendor offering the better experience.

One of our goals is to provide as neutral a benchmarking suite as possible, so while it’s impossible to avoid games sponsored by either of these companies, we can at least make an effort to achieve a blended list. As it stands, our current game list and their partners are:

(AMD) – BioShock Infinite
(AMD) – Sleeping Dogs
(AMD) – Crysis 3
(NVIDIA) – Battlefield 3
(NVIDIA) – Metro: Last Light
(NVIDIA) – Splinter Cell Blacklist
(Neutral) – Total War: SHOGUN 2
(Neutral) – GRID 2

With that, let’s move on to a quick look at the game settings we use in our testing:

Battlefield 3

BioShock Infinite

Crysis 3

GRID 2

Metro Last Light

Sleeping Dogs

Splinter Cell Blacklist

Total War: SHOGUN 2
